  • Create categorial variable in R based on range

    - by Stedy
    I have a dataframe with a column of integers that I would like to use as a reference to make a new categorical variable. I want to divide the variable into three groups and set the ranges myself (ie 0-5, 6-10, etc). I tried cut but that divides the variable into groups based on a normal distribution and my data is right skewed. I have also tried to use if/then statements but this outputs a true/false value and I would like to keep my original variable. I am sure that there is a simple way to do this but I cannot seem to figure it out. Any advice on a simple way to do this quickly?

  • Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?

  • Variable Binding Class

    - by Davis
    Hi, I believe this is a tough one... I'm trying to create a collection of variable binding in a class. It is intended to look something like this: Dim x as integer, s as string Dim c as new VBindClass x = 1 s = "Hello" c.Add x, s Debug.Print c.value(x) '= 1 Debug.Print c.value(s) '= "Hello" Is there some function that allow us to retrieve a unique ID for a given variable and also get/set based on variable?

  • Getting 'choice' to work in Highline Ruby Gem without error and getting variable from it

    - by The Warm Jets
    I'm having a couple of problems using Highline in Ruby, and trying to get the choice element, detailed here, to work. At the moment the following code produces the error "error: wrong number of arguments (0 for 1). Use --trace to view backtrace" How do I get the variable out of choice? At the moment I have the 'do' setup, but I have no idea about how to get the variable the user has chosen out and into a variable for use elsewhere. Sorry if this is a bit beginner, I'm brand new to ruby and this is my first project, in at the deep end. Thanks in advance. if agree("Are these files going to be part of a set?

  • Access a static variable by $var::$reference

    - by chuckg
    I am trying to access a static variable within a class by using a variable class name. I'm aware that in order to access a function within the class, you use call_user_func(): class foo { function bar() { echo 'hi'; } } $class = "foo"; all_user_func(array($class, 'bar')); // prints hi However, this does not work when trying to access a static variable within the class: class foo { public static $bar = 'hi'; } $class = "foo"; call_user_func(array($class, 'bar')); // nothing echo $foo::$bar; // invalid How do I get at this variable? Is it even possible? I have a bad feeling this is only available in PHP 5.3 going forward and I'm running PHP 5.2.6. Thanks.

  • jQuery/Javascript Cookies and variable returning with value [object Object]

    - by user1706661
    I am attempting to set a cookie to a site using jQuery, ONLY if the user came from a specific site. In this case, lets use -http://referrersite.com- as the site they must come from for the cookie to be created as an example. The cookie value is being stored in a variable and everything up to this point is working fine. There is a conditional statement checking whether the user came from the referred site, if the cookie exists already and if the cookie doesn't exist and the user did not come from the referred site. If the user came from the referred site the cookie is created and stored in a variable. If the cookie already exists, it is then stored in a variable. If the cookie does not exist and the user did not come from the referred site I am assigning the variable a static string of characters - this is where the issue lies. When the variable is alerted from the non referred site and no existing cookie, it returns: [object Object], not the static string of characters. The code I am using is below: $(document).ready(function() { var referrer = document.referrer; if(referrer == "http://referrersite.com") { $.cookie("code","123456", { expires: 90, path: '/' }); cookieContainer = $.cookie("code"); alert(cookieContainer); } else if($.cookie("code")) { cookieContainer = $.cookie("code"); alert(cookieContainer); } else if($.cookie("code") == null && referrer != "http://referrersite.com") { cookieContainer = "67890"; alert(cookieContainer); } }); Please let me know if there is something I am missing as the code to me looks like it should work. Thanks!

  • Accessing initialized variable on different class C++

    - by d0pe
    I'm having some difficulties with this problem. The main idea is, I initialized a variable of class type B in class A, class A.h has the variable Z declared as public, like B *Z; In class A.cpp, I initialized it as Z = new B(); Now, I want to access that variable from class C and I'm unable to do so. C.h includes A.h and B.h

  • Variable pre-fixes, Visual Studio 2010 onwards?

    - by thedixon
    I'm a bit bewildered on this subject, as I relate variable prefixes to being a thing of the past now, but with Visual Studio 2010 onwards (I'm currently using 2012), do people still do this and why? I only ask because, these days, you can hover over any variable and it'll tell you the variable type and scope. There's literally no requirement for pre-fixing being there for readability. By this I mean: string strHello int intHello etc. And I'm being language/tool biased here - as Visual Studio takes a lot of the legwork out for you in terms of seeing exactly what type the variable is, including after conversions in the code. This is not a "general programming" question.

  • /etc/enviorment not being read into PATH variable

    - by Dan
    In Ubuntu the path variable is stored in /etc/enviorment. This is mine (I've made no changes to it, this is the system default): $ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" but when I examine my PATH variable: $ echo $PATH /home/dan/bin:/home/dan/bin:/bin:/usr/bin:/usr/local/bin:/usr/bin/X11 You'll notice /usr/games is missing (it was there up until a few days ago). My /etc/profile makes no mention of PATH. My ~/.profile is the default and only has: if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi This only happens in gnome, not in tty1-6. This is missing from both gnome terminal and when I try to call applications from the applications dropdown. Anyone know what could be causing this? Thanks.

  • Python version priority in OSX/UNIX PATH environment variable

    - by mindthief
    Hi all, I want my system to use /usr/bin/python, but it's currently using /opt/local/bin/python, which points to /usr/bin/python2.6. I tried modifying the PATH variable in my .bashrc as PATH=~/bin:$PATH ...and then set a symbolic link in ~/bin to point to /usr/bin/python. i.e. ~/bin/python --> /usr/bin/python I figured this might prioritize this symlink over the /opt/local version if it came before the other one in the PATH variable, but when I opened a new shell I still found python pointing to /opt/local/bin. Any advice on a good way to get the system to use /usr/bin/python? Also, I usually use ipython as opposed to python directly. I'm assuming that if the system starts to use the correct version of python then ipython would also use that version? If not, how could I also get ipython to use the correct version? Thanks!

  • where.exe does not find OpenSSL libs when %ProgramFiles% variable is used in the PATH environment variable

    - by Piotr Dobrogost
    I installed both 32bit and 64bit version of OpenSSL libs on Vista x64. The 32bit version was installed in c:\Program Files (x86)\OpenSSL and the 64bit version was installed in c:\Program Files\OpenSSL. Then I added the entry %ProgramFiles%\OpenSSL to the PATH environment variable. %ProgramFiles%\OpenSSL is expanded to c:\Program Files (x86)\OpenSSL for 32bit programs and it's expanded to c:\Program Files\OpenSSL for 64bit programs. The idea is to have 32bit programs use 32bit version of OpenSSL libs and 64bit programs use 64bit version. I wanted to check if this works by running 32bit cmd.exe and issuing where ssleay32.dll and then by running 64bit cmd.exe and issuing the same. However in both cases I get the error INFO: Could not find files for the given pattern(s). What's wrong? This is a follow up to Different PATH environment variable for 32bit and 64bit Windows - is it possible?

  • Need to set mailx variable to specify the From address

    - by user256817
    Running Oracle Linux 5.8 (which is just re-branded RedHat EL 5.8) I must change the From address. But we have scripts that use mailx which cannot be re-written to use any extra flags, so I'd like to use internal variables instead, which I see on the linux.die.net manpage on mailx is an alternative to the -r flag: -r address Sets the From address. Overrides any from variable specified in environment or startup files. Tilde escapes are disabled. The -r address options are passed to the mail transfer agent unless SMTP is used. This option exists for compatibility only; it is recommended to set the from variable directly instead. (Source: http://linux.die.net/man/1/mailx) How can we use these mailx variables? I tried adding this to /root/.mailrc, no go: set [email protected] I also added that to /etc/mail.rc with no gold. So I am turning to you, SuperUsers...

  • Modify PATH variable for X11 during log-in

    - by user1028435
    I am working on some lab computers (read: no administrative rights) that, if I log in, I need to change the PATH variable as X11 starts. The reason is that I need to change the PATH variable at this time, as opposed to later, is that the Print Screen command seems to "bind" during login (forgive my bad explanation of this). Currently, I have a .bashrc script as a workaround: #!/bin/bash export PATH=/home/username/bin:$PATH I can make it work by starting a new X, but I was wondering if it is possible to change upon login. cat /etc/redhat-release tells me my distribution is: Red Hat Enterprise Linux Client release 5.8 (Tikanga)

  • set a global environment variable in linux that sticks when going root

    - by Scott
    When I SSH into a linux box, I want to have the /etc/profile file save the results of the whoami command to a global environment variable. if I were to go root with the command sudo su -, I do not want that command to run again when gonig root, I want it to stick with the result of whoami as my regular username from before I went root, and I need to access that variable as the root user even though it will run the /etc/profile file again when I go root. What can I do to only run that command once in the /etc/profile command?

  • Need help troubleshooting highly variable ping times

    - by Elliot.Bradshaw
    I'm at work using Citrix (think Remote Desktop) to connect to client sites. With my job I have to write a fair bit of code while I'm connected remotely via Citrix, so the latency of my internet connection is important. If I'm getting ping times above 250ms, then it becomes almost impossible to scroll, click or type with accuracy. Recently my Comcast business internet has been exhibiting highly variable ping times. If I ping google.com, I'll get pings that range from 9ms all the way up to 1300ms. The problem seems to be at its worst during the hours of 1PM to 4:30PM. Outside of those hours and the variance in pings settles down, mostly between 9ms and 50ms. The signal to noise ratio and upstream power are both fine on my modem--the values are here: http://pastebin.com/D4hWGPXf I ran a trace route from my computer to google.com (the results of which are here: http://pastebin.com/GcdjYvMh) and did another test ping to the IP of the first hop outside of our local network (73.98.44.1)--the variance in ping times existed in exactly the same manner as if I were pinging Google. Connecting directly to the cable modem by CAT5 makes no difference. Here is a screenshot demonstrating the variance of the ping times: http://postimage.org/image/haocdeauv/full/ -- as you can see it can get pretty bad. Three Comcast techs have been out (two of them were here when the problem wasn't happening) and they as well as the regional tier 2 Comcast support were unable to diagnose the problem. I now have a ticket open with tier 3 support, but have yet to hear back from them. Does anyone know what could cause these sorts of problems or have any idea from the traceroute above where it could be originating? The regional tier 2 guy tried to tell me that what I'm seeing is normal--are highly variable ping times like that ever acceptable? Anything I should ask Comcast to do or look at to get this problem fixed? Any tips/advice much appreciated! Edit: This is Comcast cable internet at a small start-up, we've ruled out congestion in our private LAN as a cause (i.e., no one's watching YouTube when the pings become variable). Update: Tier 3 Comcast support advised swapping out the modem, a tech came here today and did that--same problem persists.

  • Mac OS X keeps "old" environment variable around

    - by Xymak1y
    So far I had /Applications/play-1.2.5/ added to my $PATH variable. Now I'm working with 2.2.1, which I installed in /Applications/play-2.2.1 and changed in ~/.bash_profile (which is getting sourced at startup). However, when printing $PATH, 1.2.5 is somehow still around: mbp:~ user$ echo $PATH /usr/local/share/npm/bin:/Applications/play-2.2.1:/usr/local/heroku/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Applications/play-1.2.5:/Applications/XAMPP/xamppfiles/bin/:/opt/X11/bin As far as I now, I only entered $PATH variables in .bash_profile, which looks like this: mbp:~ user$ cat .bash_profile source ~/.git-completion.bash ### Added by the Heroku Toolbelt export PATH="/usr/local/heroku/bin:$PATH" ### Play Framework export PATH="/Applications/play-2.2.1:$PATH" export PATH="/usr/local/share/npm/bin:$PATH" I'm also not sure where the XAMPP extension to the variable comes from. Can I see somewhere which other files are being sourced on startup?

  • Python regular expressions matching variables to end of line

    - by None
    When you use variables (is that the correct word?) in python regular expressions like this: "blah (?P\w+)" ("value" would be the variable), how could you make the variable's value be the text after "blah " to the end of the line or to a certain character not paying any attention to the actual content of the variable. For example, this is pseudo-code for what I want: >>> import re >>> p = re.compile("say (?P<value>continue_until_text_after_assignment_is_recognized) endsay") >>> m = p.match("say Hello hi yo endsay") >>> m.group('value') 'Hello hi yo' Note: The title is probably not understandable. That is because I didn't know how to say it. Sorry if I caused any confusion.
